سنن النسائي

It was narrated that Hudhaifah said: "I prayed with the Messenger of Allah (ﷺ) one night. He started reciting Surat Al-Baqarah and he recited one hundred verses, then did not bow, rather he continued. I thought: 'He will complete it in two rak'ahs, but he continued.' I thought: 'He will complete it and then bow,' but he continued until he recited Surat An-Nisa', then Al Imran. Then he bowed for almost as long as he had stood, saying while bowing: 'Subhan Rabbial-azim, Subhan Rabbial-azim, Subhan Rabbial-azim ( Glory be to my Lord Almighty, Glory be to my Lord Almighty, Glory be to my Lord Almighty).' Then he raised his head and said: 'Sami Allahu liman hamidah (Allah hears the one who praises Him). Then he prostrated and made his prostration lengthy, saying: "Subhan Rabbial-A'la, Subhan Rabbial-A'la, Subhan Rabbial-A'la (Glory be to my Lord Most High, Glory be to my Lord Most High, Glory be to my Lord Most High). And he did not come to any verse that spoke of fear or glorifying Allah, the Mighty and Sublime, but he said something appropriate."
